On 12 August, Chelsea suffered a nightmare start to their Premier League title defence, losing 3–2 at home to [[Burnley F.C.|Burnley]], who had only won once away from home in the previous season. Chelsea's performance was marred by two of their players receiving red cards, the first being captain [[Gary Cahill]] in the early stages of the game, and the second being [[Cesc Fàbregas]] towards the closing stages of the match.

Morata would later add to Chelsea's goal tally with a header in the 40th minute, scoring his second league goal of the season.

The most notable of these was Chelsea's attempt to sign Everton midfielder [[Ross Barkley]], agreeing a fee with Everton only for Barkley to reject the move.<ref>{{cite news|url=http://www.bbc.co.uk/sport/football/41119055|title=Ross Barkley rejects Chelsea transfer|publisher=BBC Sport|date=31 August 2017}}</ref> Another English transfer target, Arsenal midfielder [[Alex Oxlade-Chamberlain]], also rejected a move to Chelsea after a fee had been agreed between the two clubs, with Oxlade-Chamberlain instead choosing a move to [[Liverpool F.C.|Liverpool]] on deadline day.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41077833|title=Alex Oxlade-Chamberlain: Arsenal man turns down £40m Chelsea move|publisher=BBC Sport|date=29 August 2017}}</ref><ref>{{cite web |url=http://www.bbc.co.uk/sport/football/41098529 |title=Alex Oxlade-Chamberlain: Liverpool sign Arsenal midfielder for £35m |work=[[BBC Sport]] |date=31 August 2017 |accessdate=31 August 2017}}</ref> ''The Blues'' had also reportedly been close to signing Swansea City striker [[Fernando Llorente]] at one point throughout deadline day, only to miss out on signing him to their rivals Tottenham.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41107780|title=Tottenham complete signing of Fernando Llorente|publisher=BBC Sport|date=31 August 2017}}</ref>
===September===
On 1 September, [[Loïc Rémy]] left the club to sign for [[La Liga]] club [[UD Las Palmas|Las Palmas]] on a two-year contract for a reported free transfer. <ref>{{Cite news|url=http://www.chelseafc.com/news/latest-news/2017/09/remy-moves-on.html|title=Remy moves on|publisher=Chelsea Official Site |date=1 September 2017 |accessdate=1 September 2017}}</ref>
On 9 September, Chelsea earned a 2–1 away victory at Leicester City, making it a third Premier League victory in a row. [[N'Golo Kanté]] scored the second goal for ''the Blues'' against his former club. Davide Zappacosta made his debut for Chelsea while Eden Hazard returned from injury, coming on as a substitute.<ref>{{cite web|url=http://www.bbc.com/sport/football/41133348 |title=Leicester City 1-2 Chelsea |date=9 September 2017 |publisher=BBC Sports}}</ref>
On 12 September, Chelsea marked their return to the UEFA Champions League with a 6–0 thrashing of Azerbaijani champions [[Qarabağ FK|Qarabağ]], who made their first ever appearance in Europe's elite competition. Goals from [[Pedro (footballer, born July 1987)|Pedro]], [[César Azpilicueta]], Tiemoué Bakayoko, [[Michy Batshuayi]] as well as a goal from Zappacosta on his first start for Chelsea, and an own goal by Qarabağ player [[Maksim Medvedev]], sent ''the Blues'' to the top of their group after the first round of fixtures.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41216361|title=Chelsea 6–0 Qarabag|publisher=BBC Sport|date=12 September 2017}}</ref>
On 17 September, Chelsea hosted rivals Arsenal at Stamford Bridge, who managed to emerge with a point by drawing 0–0 with ''the Blues''. It was a frustrating match for Chelsea, who created several opportunities to score but could not find a cutting edge against a well-drilled Arsenal side. The game was also marred by David Luiz receiving a red card in the second half for a high tackle on [[Sead Kolašinac]], with the defender set to miss Chelsea's next three matches as a result. His red card amounts to Chelsea's third red card of the season. The result sees ''the Blues'' remaining in third place, three points behind joint leaders Manchester United and Manchester City.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41216718|title=Chelsea 0–0 Arsenal|publisher=BBC Sport|date=17 September 2017}}</ref>
On 20 September, Chelsea hosted [[Nottingham Forest F.C.|Nottingham Forest]] in the third round of the [[2017–18 EFL Cup|EFL Cup]], defeating the Championship club 5–1 to advance to the next round. Amongst the goalscorers was Batshuayi, who completed a hat-trick with a goal in the first half and two further goals in the second half. [[Kenedy (footballer)|Kenedy]] and Charly Musonda also got on the scoresheet, and youngster [[Ethan Ampadu]] made his first senior Chelsea appearance as a second-half substitute.<ref>{{Cite news|url=http://www.bbc.co.uk/sport/football/41249727|title=Chelsea 5–1 Nottingham Forest|publisher=BBC Sport|date=20 September 2017}}</ref>
On 21 September, the long-protracted transfer saga surrounding exiled striker [[Diego Costa]] came to an end as Chelsea agreed a fee with [[Atlético Madrid]] for his transfer, to be completed in January after the expiry of the Spanish club's transfer ban.<ref>{{Cite news|url=https://www.chelseafc.com/news/latest-news/2017/09/diego-costa-transfer-agreed.html|title=Diego Costa transfer agreed|publisher=Chelsea Football Club Official Site|date=21 September 2017}}</ref> He leaves Chelsea having scored 58 goals in 120 appearances for ''the Blues'', including 20 in the Premier League last season as Chelsea won the title.<ref>{{Cite news|url=https://www.bbc.co.uk/sport/amp/football/41369356|title=Diego Costa: Striker says he will always have 'special affection' for Chelsea|publisher=BBC Sport|date=21 September 2017}}</ref>
On 23 September, Chelsea earned a fourth Premier League victory in five matches after thrashing Stoke City 4–0 away. Álvaro Morata opened the scoring for ''the Blues'', with Pedro adding a second before half-time. Morata completed a hat-trick in the second half, Chelsea's first Premier League hat-trick since 2014, to keep ''the Blues'' in third position and within three points of the two Manchester clubs at the top of the table.<ref>{{Cite news|url=http://www.bbc.com/sport/football/41290319|title=Stoke City 0–4 Chelsea|publisher=BBC Sport|date=23 September 2017}}</ref>
On 27 September, Chelsea beat Atlético Madrid 2–1 away in a Champions League group stage match, making history in the process by becoming the first ever English club to defeat Atlético away from home in a European competition. Chelsea fell behind late in the first half after David Luiz conceded a penalty, which [[Antoine Griezmann]] converted. Morata leveled proceedings early in the second half with a header. The match looked to be finishing as a draw until Michy Batshuayi snatched a winner for Chelsea at the death. The result sees ''the Blues'' go top of Group C, four points ahead of Atlético and Roma after two match.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41379696|title=Atletico Madrid 1–2 Chelsea|publisher=BBC Sport|date=27 September 2017}}</ref>
On 30 September, three days after their Champions League heroics, Chelsea lost 1–0 at Stamford Bridge to league leaders Manchester City in a very poor performance that culminated in Chelsea only having two shots on target in the whole match. The defeat sees the gap between the two sides widen to six points, with Chelsea slipping into fourth.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41370356|title=Chelsea 0–1 Manchester City|publisher=BBC Sport|date=30 September 2017}}</ref>
===October===
On 14 October, in their first league match after the international break, Chelsea fell to a very poor 2–1 away defeat against bottom Premier League side Crystal Palace, who scored their first goals of the season and earned their first points of the season after losing their opening seven fixtures without scoring. An own goal from César Azpilicueta opened the scoring early in the first half before Tiémoué Bakayoko leveled proceedings shortly after. Palace would go on to win the match with a goal from the returning [[Wilfried Zaha]]. Chelsea were without key players N'Golo Kanté and Álvaro Morata, with Kanté picking up a hamstring injury during the international break and Morata suffering the same injury against Manchester City. The result sees Chelsea falling to nine points behind league leaders Manchester City, and they will be in fifth position after their nearest league rivals [[Arsenal F.C.|Arsenal]] play Watford regardless of the result in that match. Defeat also means that Chelsea have lost back-to-back league fixtures for the first time since last October, when they lost to Liverpool and Arsenal in succession.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41534304|title=Crystal Palace 2–1 Chelsea|publisher=BBC Sport|date=14 October 2017}}</ref>

On 30 September, three days after their Champions League heroics, Chelsea lost 1–0 at Stamford Bridge to league leaders Manchester City in a very poor performance that culminated in Chelsea only having two shots on target in the whole match. The defeat sees the gap between the two sides widen to six points, with Chelsea slipping into fourth.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41370356|title=Chelsea 0–1 Manchester City|publisher=BBC Sport|date=30 September 2017}}</ref>
===October===
On 14 October, in their first league match after the international break, Chelsea fell to a very poor 2–1 away defeat against bottom Premier League side Crystal Palace, who scored their first goals of the season and earned their first points of the season after losing their opening seven fixtures without scoring. An own goal from César Azpilicueta opened the scoring early in the first half before Tiémoué Bakayoko leveled proceedings shortly after. Palace would go on to win the match with a goal from the returning [[Wilfried Zaha]]. Chelsea were without key players N'Golo Kanté and Álvaro Morata, with Kanté picking up a hamstring injury during the international break and Morata suffering the same injury against Manchester City. The result sees Chelsea falling to nine points behind league leaders Manchester City, and they will be in fifth position after their nearest league rivals [[Arsenal F.C.|Arsenal]] play Watford regardless of the result in that match. Defeat also means that Chelsea have lost back-to-back league fixtures for the first time since last October, when they lost to Liverpool and Arsenal in succession.<ref>{{Cite news|url=http://m.bbc.co.uk/sport/football/41534304|title=Crystal Palace 2–1 Chelsea|publisher=BBC Sport|date=14 October 2017}}</ref>
